Lumber Mills

Lumber Mills

Lumber Mills traditionally trim the incoming logs and then cut them to size before Kiln drying.  The kiln process is tricky and if not done correctly the wood warps or splits and becomes waste or is downgraded reducing potential value. Knowing in advance the wood moisture can be a key to a successful kiln process. Not all logs are created equal and not even all parts of a log have the same moisture. Being able to screen them accurately could decrease the level of wood waste in your drying process, simply by sorting lots into the kilns of similar moisture.  

Two factors should be analyzed here. The wood moisture before the kiln.  Mixing dryer and wetter wood can result in warping or over/under drying of some boards.

In the kiln monitoring the temperature and RH of the kiln air is critical to prevent warping. We can do this using wired or wireless systems to best suit your facilities needs.

Multiple RH/Temperature sensors throughout the kiln will give a profile to show if air is being circulated and/or exhausted correctly. As the wood dries to the target levels the RH should be dropped slowly to prevent too quickly that will result in warping or splitting.  The key to these steps is high quality RH sensors designed for high temperature applications. Most RH sensors are not designed for high temperature and this leads to many of the RH problem in kilns.
